Find LCM of 693,120,808,765 with Prime Factorization
| 2 | 693, 120, 808, 765 |
| 2 | 693, 60, 404, 765 |
| 2 | 693, 30, 202, 765 |
| 3 | 693, 15, 101, 765 |
| 3 | 231, 5, 101, 255 |
| 5 | 77, 5, 101, 85 |
| 77, 1, 101, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 77 x 1 x 101 x 17 = 47595240
Therefore, the lowest common multiple of 693,120,808,765 is 47595240.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
693 x 120 x 808 x 765 = 51402859200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
808 : 1, 2, 4, 8, 101, 202, 404, 808
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,120,808,765, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
120:2x 2x 2x 3x 5
808:2x 2x 2x 101
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 51402859200/(1x1080)
LCM = 51402859200/1080
LCM = 47595240
Thus, we can understand that the LCM of 693,120,808,765 is 47595240.
